What's the system function?
Performance requirements: storage limit, time limit, speed limit, security, etc
System environment and resources requirements?
Reliability requirements?
Security requirements?
User interface requirements?
Cost and development requirements?
Extend requirements?
There are many cheap used computers.
I can purchase more RAM.
I can not run photoshop or illustrator on Linux.
I either need more powerful machines each with large disks, or to run them as thin client machines from a very powerful server?
Drives under about 80 GB are useless for my purposes?
a server, which can be used internally with Samba service for Windows, this can be set up as a domain controller to control network security. I then use this as a file server, a less powerful machine with Linux can act as a firewall and router with internet access, it could serve less serious files giving access to external machines if ever required. I will need some Windows machines for Photoshop and Illustrator, these need to also be powerful, as both these are heavy on resources. For the rest of the network Ubuntu may be a good option due to memory limitations, anything under 64M is now useless. All the workstations can have internet access this way if required. The thin client server machine will need quite a lot of disk space, as it will require different OS images for each machine since each will have different hardware. It also needs plenty of ram.
I can find many 32 MB RAM, can I provide multimedia interactive business education courses in 64 MB RAM Slackware Linux computer? Some can be 4 DIMM, 128 MB RAM.
(Linux Mint XFCE or Xubuntu or Fluxbuntu.) Either way, I will need more RAM to really get the performance out of the PIII processors. I will need a consistent computing environment over all of the machines?
